About formats

POT (PowerPoint Template) is the binary template format for Microsoft PowerPoint, using the same OLE2 compound document structure as PPT files. A POT file contains a complete presentation structure — slide masters, color schemes, font definitions, placeholder layouts, background designs, and default formatting — that serves as a reusable foundation for new presentations with consistent branding. When a user creates a new presentation from a POT template, PowerPoint generates a fresh untitled document pre-populated with the template's design elements while leaving the original file unmodified. The format supports all visual features available in PPT including custom slide layouts, embedded graphics, animations, transition presets, and action buttons on master slides. POT templates became central to corporate identity management in organizations that standardized their visual communications through PowerPoint, ensuring every department produced presentations with approved logos, color palettes, fonts, and layouts. One advantage is brand consistency at scale — distributing a POT file across an organization guarantees that all new presentations inherit the correct visual identity without requiring each author to manually replicate design elements. Rapid document creation is another strength: presenters start with professional layouts and focus on content rather than design, reducing preparation time. While the XML-based POTX format has replaced POT for modern workflows, the binary template format remains in use where compatibility with PowerPoint 97-2003 is required.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.
